Specification of Letters Patent.

Patented Feb.i8,1913.

Application filed May S, 1912. Serial No. 696,022.

To all whom it may concern:

Be it known that I, CHARLES E. ADAIR, a citizen of the United States,and resident of Buffalo, in the county of Erie and State of new and.This invention relates to hovers of the self-contained or portabletype, such as are adapted for use in a broodcnchamber or house withoutthe necessity of special provision thereirrfor heating the hover, theheating-means being contained entirely within the hover itself and abovethe level of the floor upon which the hover maybe placed.

The invention relates particularly to a hover, of the type in question,in which. a lamp is employed as the heating-means, and one object of theinvention is to provide the brooder with a heating-device and alampctising of a form which will heat the brooder- .chamber elfcctivelyand at the same time U ,provide for proper ventilation of the cham- 25be Another object of the invention is vide against fire risk throughoverheatin of the lamp-casing, or any other cause; and a third object ofthe invention is to produce "a construction in which the lamp may bereadily removed from the hover-chamber without disturbing the hover as awhole.

' Other objects of the invention, and the features of construction bywhich they are attained, will be set forth in connection with thefollowing description of the illustrated embodiment of the invention.

In the accompanying drawings:--Figure 1 is a transverse, vertical,median section of a hover embodying the present invention; and Fig. 2 isa horizontal section on the line in Fig. 1, showing in detail theconstruction and arrangement of the lamp-cas ing and the lamp.

In the illustrated embodiment of thein- I vention. a hover-chamber ofthe usual form is employed, this chamber comprising a circularsheet-metal upper portion having a flat top 5 and a cylindrical wall 6,and a cur tain f suitable flexible n'iaterial depend- "ing from thelower edge of the wall. This chamber is supported upon adjustable legs8.

The top 5 of the .hover-ehau'lber hasa wide central opening fromwhichdepends the cyl ndrical bodv .l of the lamp-casing,

to prothe lower end of this casing being closed airand oil-tight bymeans of an imperferate bottom 10. The opening in the top 5 and theupper end of the body 9 is normally closed by means of a removable cover11, which consists of a hollow sheet-metal men ber filled with asbestosor other material having nonconducting and fireproof qualities.

The air within the hover is heatedby means of a radiator, which is inthe formof a shallow, wide drum 12. This drum extends outwardly allaround the lamp-casing, near the upper end thereof, being in treecommunication with the lamp-casing. The

heating-lamp may be of any ordinary or ,13 with a burner 16 and achimney 17 of ordinary form.

The oil-font 13 is provided, at the top, with a peripheral flangev 14Ewhicl'i rests upon a ring 15, and this ring is connected, by means oftwo metal strips 18, with the cover 11. The ring and the strips, inconnection with the cover, constitute means by which the lamp mayberaised from the lampcas1ng, the cover being provided, for

this purpose, with a handle ill? by which it may be conveniently lifted.The parts just described also preferably constitute means for normallysupporting the lamp, the oil-- font being held a short distance abovethe bottom 10 of the lamp-casingso as to v de a space into which any oilwhich may leak from the lamp may collect, thus retaining the oil withinthe lan'lp-casiug and guarding against risk of fire from this cause.

The air by which the combustion of the lamp issupported is admitted tothe lampcasing through lateral air-openings 19, which are protected bywire-gauze, this gauze having a. mesh sutlicient-ly line to prevent thepassage of flame through the airopenings. The heated products ofcombustion fromthe lamp, after their passage through the radia or ashereinafter de scribed, are finally conducted from the lamp- (asingthrough a vent-pipe 20 which passes upwardly through the cover ll, andthis pipe is also provided with a fire-screen 21. of wire-gauze.

The temperature of the cover is regulated by means of an opening in thetop 5, controlled by a damper 23 of ordinary form, this damper beingautomatically opened and closed through a mechanism comprising a timecontributing to the ventilation of the lever 24 and a rod 25 connectingthe damper with a thermostat: 26, which is located in the upper part ofthe hover-chamber.

The lower end of the vent-pipe 20 projects downwardly to a point'bstantially below the radiator 12, and by this arrangement a propercirculation of hot air within the radiator is secured. The products ofcombustion from the lamp, issuing from the upper end of the chimney 17,strike against t-helower surface of the cover 11 and then spread in alldirections into the radiator and along the upper wall thereof, and theyare more or lesscooled by contact with the walls of the radiator theydescend at the periphery of the radiator and then pass inwardly alongthe lower wall of the radiator,

[thus returning to the lamp-casing. The partially cooled gases thendescend within the lamp casing to the lower end of the ventpipe, throughwhich they are finally discharged. The downward extension of thevent-pipe prevents the products of combustion from at once issuingthrough the outlet, causing them first to ascend and flow through theradiator, as just described.

The provision of air-inlet openings in the sides of the lamp-casingresults in the ventilation of the hover-chamber, since a constant flowof air is produced through the chamber to these openings, and the flowof thisair also acts to prevent overheating of the walls of thelamp-casing, thus maintaining it at a temperature which permits thechicks to-nestle against the casing without injury.

By the arrangement of the lamp-casing and the radiator just describedthe hoverchamber is efliciently heated, while at the sametime the lampis inclosed within a casing which is entirely fire-tight. When it isnecessary to trim or fill the. lamp this may be conveniently done byraising the cover 11 and the lamp from the lamp-casing, and

I for this purpose it is necessary only to have its access to the top ofthe hover, the hoverchamber being in no way disturbed in the operatibnSince the lamp-casing terminates at or above the level of the floor orsurface upon which the hover is supported, it is unnecessary to provideany opening or recess in this floor, to receive the lamp casmg so thatthe hover may be used in any closed compartment and moved from place toplace as convenience may requine, or it may, in fact, be used in theopen ail}, being complete in itself.

When the temperature within the hoverchamber rises above a predetermineddegree the thermostat 26 opens the damper 23 auto-- matically, andpermits more or less heated air to discharge from the hover-chamber,thus automatically regulating the temper-w ture within this chamber andat the same hover chamber and extendin downuardlv.

from the top of the chamber, the lamp-ca ing being closed at the top, awide, shallow, annular radiator projecting horizontally around thelamp-casing, near the top thereof, and closed except at the center,where it freely communicates with the casing, and a vent-pipe passingupwardly through the top of the lamp-casing near the side thereof, thelower end of the vent-pipe being at a sub stantial distance below theradiator so as not to receive directly the heated gases from the lamp.
